法珀滤光器在我国天文界得到了越来越广泛的应用,目前云南天文台抚仙湖太阳观测站已购进两台法珀滤光器,准备用于1 m新真空太阳望远镜的光谱观测中。由于国内对法珀滤光器研究比较少,国外相关资料尚不能查询到,因此了解其控制系统,不仅是自行研制法珀滤光器的需要,也是日常工作中必须的基础。针对这一趋势,在简介法珀滤光器原理的基础上,介绍了法珀滤光器的控制系统,并对控制系统数字前端模数转换精度要求进行研究。通过计算法珀平行板控制精度,最终选出符合要求的模数转换器。 

Other Abstract

Fabry-Perot Interferometers has been more and more widely used in China' s astronomical community. At present, the Fuxian Lake Solar Observatory at the Yunnan Observatory has purchased two FPI for use in the spectral observation of the 1m new vacuum solar telescope. As the domestic research on FPI is still relatively small, overseas inquiries to relevant information is not yet accessable. Therefore, understanding its control system is not only needed to research FPI, but also the necessary foundation in daily work. In this paper, a basic review of FPI control system is given, and research is carried out on the analog-digital converting accuracy requirements in the digital front-end of the control system. We calculate the accuracy of the F-P parallel board control and finally select the AD converter that meets the requirements.
